Element3; Coated Rotor Product Line Details

The Element3; Coated Rotor line by Raybestos features a protective coating that helps resist corrosion and extends rotor life. This coating is particularly beneficial for vehicles exposed to harsh weather or road conditions, such as the Chevrolet Silverado 3500 and GMC Sierra 3500 HD. The 56992FZN rotor combines this coating with a vented design to optimize heat dissipation and maintain braking efficiency over time.

Technical Specifications and Features

This disc brake rotor is vented to improve airflow and reduce heat buildup during braking, which helps prevent warping and extends rotor lifespan. The drum-in-hat design integrates a parking brake drum within the rotor, making it suitable for heavy-duty applications. With eight mounting bolt holes arranged on a 6.500-inch bolt circle diameter, the rotor ensures secure fitment on compatible Chevrolet and GMC trucks. The nominal thickness of 1.185 inches (30.100 mm) provides a solid braking surface, while the discard thickness of 1.122 inches (28.500 mm) indicates when replacement is necessary to maintain safety and performance.

Applications and Problem Solving

• Replacement for worn or warped rotors on Chevrolet Silverado 3500 and GMC Sierra 3500 models
• Addresses brake fade caused by excessive heat during heavy towing or hauling
• Resolves vibration or pulsation issues due to uneven rotor surfaces
• Prevents corrosion-related rotor damage in harsh environments
• Supports parking brake functionality with integrated drum-in-hat design

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the mounting bolt hole pattern and center hole diameter match your vehicle specifications. Use proper torque settings on the eight mounting bolts to secure the rotor. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 1.122 inches (28.500 mm).
